Cleaning digital camera
Before wiping off the lens, hold the camera upside down and gently blow off any grit and lose dust particles. Next lightly wipe the lens and other camera parts with a soft, dry cloth or lens cleaning paper.
The best camera cleaning cloth is made of microfiber, which should be stored in a plastic baggie when not in use. Lens tissue, a swatch from a cotton t-shirt or a soft handkerchief can also be used. Paper towels, napkins and facial tissue should not be used to clean the lens.
If your camera needs extensive cleaning, have it done professionally.
